Not really… I think the closest way I can explain it is that you’d be thinking in an unstructured and abstract fashion. Like how some brilliant artists can create amazing art and yet be completely unable to manage their life’s most mundane things like feeding themselves and personal finances. They need somebody to take care of them.
Similarly, some autistic people or savants can do things people think are impossible, but they lack in mental faculties we all take for granted.
Going into that state of mind is operating at a level that simply isn’t practical. The whole world disappears while you turn inward and broaden your perception to a place where everything makes perfect sense but cannot be put into words.
Obviously it’s a temporary state of mind, so you can switch back to your default (auto-pilot) state. But as soon as you do, like trying to remember your dreams, only a fraction of the epiphanies you experienced stick. Meaning you can only write down that fraction. And then you’ll have to go back into it and get another fraction.
It’s extremely frustrating to experience a sensation of complete comprehension, literally feeling all the pieces of the puzzle falling into place, only to have them fade away like ice in warm water when you try to write them down.
I tried describing what I realized while in one of those states to another philosopher a while back and he broke off contact for a month. When I asked him why, he said he did not know what to say because it seemed to be an explanation for something that defied explanation.
Anyways… so, how about them Yankees? 
I think the reader can actually read the emotion that I was feeling when I wrote this. Both the wonder and frustration.
